DuPont AFFINITY TankMix is for use on wheat, barley, oat, triticale, post-harvest burndown, pre-plant burndown and fallow in most states. Check with your state extension service or Department of Agriculture before use, to be certain AFFINITY TankMix is registered in your state.

AFFINITY TankMix is to be used in a tank mix with other suitable registered herbicides to provide selective postemergence control of certain broadleaf weeds in wheat (including durum), barley, oat, triticale, post-harvest burndown, preplant burndown and fallow. AFFINITY TankMix herbicide (with TotalSol soluble granules) at 0.6 oz/a to 1.0 oz/a can be used alone or in a tankmix in the state of Arizona for control of broadleaf weeds in wheat, barley and triticale, and at 0.6 to 0.75 oz/a in oat. AFFINITY
TankMix is a soluble granule to be mixed in water or other recommended carrier and applied as a uniform broadcast spray. It is noncorrosive, nonflammable, nonvolatile and does not freeze.

Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following:
- Do not apply, drain or flush equipment on or near desirable trees or other plants or on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots.
- Do not use on lawns, walks, driveways, tennis courts, or similar areas. Prevent drift of spray to desirable plants.
- Do not apply AFFINITY TankMix by air in the state of New York.
- Do not use low rates of liquid fertilizer as a substitute for a surfactant.
- Do not use with liquid fertilizer solutions with a pH less than 3.0.
- Do not apply AFFINITY TankMix within 60 days of crop emergence where an organophosphate insecticide has been applied as an in-furrow treatment because crop injury may result.
- Do not use AFFINITY TankMix plus "Malathion" because crop injury will result.
- Do not tank mix AFFINITY TankMix with “Achieve” herbicide”.
- Do not use a tank mix of AFFINITY TankMix with a bromoxynil containing herbicide with "Puma" on two-row malting barley.
- Do not use on "Ogle", "Porter" or "Premier" varieties in spring oat as crop injury can occur.
- Do not tank mix "Hoelon" 3EC herbicide + AFFINITY TankMix herbicide when foxtail is the major grassy weed in the field - Use sequential treatments.
- Do not apply more than 0.75 ounce of AFFINITY TankMix per acre per year on oat.
- Sequential treatments of AFFINITY TankMix may be made provided the total amount of AFFINITY TankMix applied to the wheat, barley or triticale does not exceed 1.8 ounces per acre per year.
- Sequential treatments of AFFINITY TankMix may be made provided the total amount of AFFINITY TankMix applied in fallow does not exceed 1.8 ounces per acre per year.
- Sequential treatments of AFFINITY TankMix may also be made provided the total amount of AFFINITY TankMix applied during one fallow/preplant season does not exceed 1.8 ounces per acre per year.
AFFINITY TankMix must not be applied to wheat, barley, oat or triticale that is stressed by severe weather conditions, drought (including low levels of subsoil moisture), low fertility, water-saturated soil, disease, or insect damage, as crop injury may result. Risk of injury is greatest when crop is in the 2 to 5-leaf stage. Severe winter stress, drought, disease, or insect damage following application also may result in crop injury.
- Do not apply to wheat, barley, oat or triticale crops underseeded with another crop.
- Do not harvest within 45 days of the last application in wheat (including durum), barley, winter oat and triticale.
- Do not harvest within 45 days of the last application in spring oat.

Injury to or loss of adjacent sensitive crops, desirable trees or vegetation may result from failure to observe the following:
- Take all necessary precautions to avoid all direct or indirect contact (such as spray drift) with non-target plants or areas.
Carefully observe all sprayer cleanup instructions both prior to and after using this product, as spray tank residue may damage crops other than wheat, barley, oat or triticale.
Dry, dusty field conditions may result in reduced control in wheel track areas.
Wheat, barley, oat and triticale may differ in their response to various herbicides. DuPont recommends that you first consult your state experiment station, university, or extension agent as to sensitivity to any herbicide. If no information is available, limit the initial use of DuPont AFFINITY TankMix to a small area.
Under certain conditions, such as heavy rainfall, prolonged cold weather (daily high temperature less than 50oF), or wide fluctuations in day/night temperatures prior to or soon after AFFINITY TankMix application, temporary discoloration and/or crop injury may occur. To reduce the potential of crop injury, tank mix AFFINITY TankMix with 2,4-D (ester formulations perform best–see “Tank Mixtures” section of this label) and apply after the crop is in the tillering stage of growth.

Best results are obtained when AFFINITY TankMix is applied to young, actively growing weeds. The use rate will depend on weed spectrum and size of weed at time of application. The degree of control and duration of effect are dependent on rate used, sensitivity and size of target weed and environmental conditions at the time of and following application. AFFINITY TankMix stops growth of susceptible weeds rapidly. However, typical symptoms of dying weeds (discoloration) may not be noticeable for 1-3 weeks after application (2-5 weeks for wild garlic, when present) depending on the environmental conditions and weed susceptibility. Warm, moist conditions following treatment promote the activity of AFFINITY TankMix, while cold, dry conditions delay the activity. Weeds hardened-off by cold weather or drought stress will be less susceptible.
A vigorous growing crop will aid weed control by shading and providing competition for weeds. However, a dense crop canopy at time of application can intercept spray and result in reduced weed control. Weeds may not be adequately controlled in areas of thin crop stand or seeding skips.
Applications made to weeds that are in the cotyledon stage, larger than the size indicated, or to weeds under stress may result in unsatisfactory control.
AFFINITY TankMix may injure crops that are stressed from adverse environmental conditions (such as extreme temperatures or moisture), abnormal soil conditions, or cultural practices. In addition, different varieties of the crop may have differing levels of sensitivity to treatment with AFFINITY TankMix under otherwise normal conditions.
Treatment of sensitive crop varieties may injure crops. To reduce the potential of crop injury, tank mix AFFINITY TankMix with 2,4-D (ester formulations perform best – see "TANK MIXTURES" section of this label) and apply after the crop is in the tillering stage of growth.
Weed control may be reduced if rainfall or snowfall occurs soon after application. Several hours of dry weather are needed to allow AFFINITY TankMix to be sufficiently absorbed by weed foliage.

AFFINITY TankMix, which contains the active ingredients thifensulfuron methyl and tribenuron methyl, is a Group 2 herbicide based on the mode of action classification system of the Weed Science Society of America.
When herbicides with mode of action classifications that affect the same biological sites of action are used repeatedly over several years to control the same weed species in the same treatment area, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that area. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product affecting a different biological site of action.
To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that affect a different site of action. Weed escapes that are allowed to go to seed and movement of plant material between treatment areas on equipment will promote the spread of resistant biotypes.
It is advisable to keep accurate records of pesticides applied to individual fields to help obtain information on the spread and dispersal of resistant biotypes. Consult your agricultural dealer, consultant, applicator, and/or appropriate state agricultural extension service representative to determine appropriate actions for treating specific resistant weed biotypes in your area.

DuPont recommends the use of Integrated Pest Management (IPM) programs to control pests. This product may be used as part of an IPM program that can include biological, cultural, and genetic practices aimed at preventing economic pest damage. Application of this product should be based on IPM principles and practices including field scouting or other detection methods, correct target pest identification, population monitoring, and treating when target pest populations reach locally determined action thresholds. Consult your state cooperative extension service, professional consultants or other qualified authorities to determine appropriate action treatment threshold levels for treating specific pest/crop systems in your area.

DuPont AFFINITY TankMix herbicide provides selective postemergence control of certain broadleaf weeds in wheat (including durum), barley, oat, triticale, post-harvest burndown, pre-plant burndown and fallow.

Allow at least 7 days between application and grazing of treated forage. In addition, allow at least 7 days between application and feeding of forage from treated areas to livestock. Allow at least 30 days between application and feeding of hay from treated areas to livestock. Harvested straw may be used for bedding and/or feed. Allow at least 45 days between application and harvesting of grain.

AFFINITY TankMix can be measured using the AFFINITY TankMix volumetric measuring cylinder provided by DuPont. The degree of accuracy of this cylinder varies by +/- 7.5%. For more precise measurement, use scales calibrated in ounces.

For optimum spray distribution and thorough coverage, use flat-fan or low-volume flood nozzles.
- For best performance, select nozzles and pressure that deliver MEDIUM spray droplets.
- Nozzles that deliver COARSE spray droplets may be used to reduce drift, provided spray volume is increased to maintain coverage on small weeds. For optimal product performance and minimal spray drift, adjust the spray boom to the lowest possible spray height recommended in manufacturers’ specifications.
- Overlaps or starting, stopping, slowing, and turning while spraying may result in crop injury.
- For flat-fan nozzles, use a spray volume of at least 5 gal per acre (GPA).
- For flood nozzles on 30" spacings, use at least 10 GPA, flood nozzles no larger than TK10 (or the equivalent), and a pressure of at least 30 psi. For 40" nozzle spacings, use at least 13 GPA; for 60" spacings use at least 20 GPA. It is essential to overlap the nozzles 100% for all spacings.
- "Raindrop RA" nozzles are not recommended for AFFINITY TankMix herbicide applications, as weed control performance may be reduced.
- Use screens that are 50-mesh or larger.

Use nozzle types and arrangements that provide optimum spray distribution and maximum coverage.
- Use 2 to 5 GPA
- Use at least 3 GPA in Idaho, Oregon, or Utah

Do not apply DuPont AFFINITY TankMix by air in the state of New York.
When applying AFFINITY TankMix by air in areas adjacent to sensitive crops, use solid stream nozzles oriented straight back. Adjust the swath to avoid spray drift damage to sensitive crops downwind and/or use ground equipment to treat the border edge of fields. See the "SPRAY DRIFT MANAGEMENT" section of this label.

For specific application equipment, refer to the manufacturer’s instructions for additional information on GPA, pressure, speed, nozzle types and arrangements, nozzle heights above the target canopy, etc.
Be sure to calibrate air or ground equipment properly before application. Select a spray volume and delivery system that will ensure thorough coverage and a uniform spray pattern with minimum drift. Use higher spray volumes to obtain better coverage when crop canopy is dense. Avoid swath overlapping, and shut off spray booms while starting, turning, slowing, or stopping, to avoid injury to the crop. Do not make applications using equipment and/or spray volumes or during weather conditions that might cause spray to drift onto nontarget sites. For additional information on spray drift refer to the "SPRAY DRIFT MANAGEMENT" section of this label.
Continuous agitation is not required for AFFINITY TankMix but may be required to keep tank-mix partners in solution or suspension. Refer to tank-mix partner labels for additional information.

Before Spraying AFFINITY TankMix
The spray equipment must be clean before AFFINITY TankMix is sprayed. Follow the cleanup procedures specified on the labels of the previously applied products. If no directions are provided, follow the steps outlined in the "AFTER SPRAYING AFFINITY TankMix" section of this label.

At the End Of the Day
It is recommended that during periods when multiple loads of AFFINITY TankMix herbicide are applied, at the end of each day of spraying, the interior of the tank be rinsed with fresh water and then partially filled, and the boom and hoses flushed. This will prevent the buildup of dried pesticide deposits, which can accumulate in the application equipment.

After Spraying AFFINITY TankMix and Before Spraying Crops Other Than Wheat, Barley, Oat or Triticale
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment immediately following applications of AFFINITY TankMix as follows:
1. Empty the tank and drain the sump completely.
2. Spray the tank walls with clean water using a minimum volume of 10% of the tank volume. Circulate the water through the lines, including all by-pass lines, for at least two minutes. Flush the boom well and empty the sprayer. Completely drain the sump.
3. Repeat step 2.
4. Remove the nozzles and screens and clean separately in a bucket containing water.
The rinsate solution may be applied back to the crop(s) specified on this label. Do not exceed the maximum-labeled use rate. If cleaners are used, consult the cleaner label for rinsate disposal instructions. If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility.

1. Steam-cleaning aerial spray tanks is recommended to facilitate the removal of any caked deposits.
2.When AFFINITY TankMix is tank mixed with other pesticides, all cleanout procedures for each product should be examined and the most rigorous procedure should be followed.
3. Follow any pre-cleanout guidelines recommended on other product labels.
